Washington, DC (LifeNews.com) -- More details are emerging about a terrorism dictionary the administration of President Barack Obama put together in March. The newly-revealed document comes on the heels of a report the Department of Homeland Security sent out saying pro-life advocates were right-wing extremists.

The latest report to cause national outrage is a document known as the "Domestic Extremism Lexicon," essentially a terrorism and political extremism dictionary for the Obama administration's internal use.

The March 26, 2009 document features numerous definitions and the headline "antiabortion extremism," appears on page two of the eleven-page manual.

The definition reads: "A movement of groups or individuals who are virulently antiabortion and advocate violence against providers of abortion-related services, their employees, and their facilities. Some cite various racist and anti-Semitic beliefs to justify their criminal activities."

A Washington Times report indicates the terrorism dictionary was recalled within hours after the Obama administration released it.

Amy Kudwa, Homeland Security spokeswoman, told the newspaper the dictionary "was not an authorized I&A product, and it was recalled as soon as management discovered it had been released without authorization."

Although she said the dictionary "is not, nor was it ever, in operational use," Kudwa did not appear to dispute its existence or that the Obama administration compiled it.

Kudwa says the terrorism dictionary would not have been put together following the outcry over a report sent to police and sheriffs offices nationwide saying people who oppose abortion are potential terrorists and extremists.

"Since this happened prior to our last experience, our new internal protocols were obviously not in place," she said.

Rep. Peter King, a New York Republican congressman who is the ranking member on the House Homeland Security Committee, told the Times he was furious with the news of the dictionary.

He said it "causes further concern that Congress needs to get to the bottom of exactly how DHS determines what intelligence products to distribute to law enforcement officials around the country."

In an interview following the release of the first report, DHS Secretary Janet Napolitano defended including pro-life advocates and saying "opponents of abortion" are likely to engage in extremism or terrorism.

King asked Napolitano whether the department has active investigations on "anti-abortion groups" concerning potential extremism or terrorism and the Obama cabinet official declined to answer.

She said she would not comment on the activities of the department and claimed that pro-life groups have a "history" of such actions.

Napolitano said that, although "people have different points of view about abortion" and that the Obama administration values free speech rights, some pro-life advocates cause her agency concern.

"On the other hand, at the very edge of the [abortion] debate, at the very edge are the extremist groups that have committed violent crimes," said Napolitano. "They've committed bombings and the like."
